Roma's Serie A match at Sampdoria on Saturday has been postponed with severe thunderstorms forecasted to hit Genoa.
A replacement date was not immediately announced, although it's unlikely that the game can be played before mid-October because of Roma's participation in the Champions League.
Authorities in Genoa have issued a severe storm alert for the entire weekend, with severe rain and flooding expected for the port city.
Sampdoria won their opening two matches of the season while Roma won one and lost one.
Roma host Atletico Madrid in the Champions League on Tuesday.
